I am 18 and new to electronics. I need a circuit(s) to solve the following problem: I have a system of 8 parallel inputs (switches) 0-7 which control 8 parallel outputs (low voltage servos). I want to be able to press any combination of switches, ie I press switches 7, 1, 6 & 0 and servos 7, 1, 6 & 0 are activated in that exact order, when I hit a 'GO' Button, ie I have pressed my 4 switches 7, 1, 6 & 0 and on pressing 'Go' once servo 7 is activated, press 'Go' again 1 is activated etc. So, my input switches are like pre selectors which decide what corrosponding servo will active on hitting 'GO' and in which order. I would also need a 'Clear' so I could start again. I am swamped by the information available, do i go digital or analog? Do I need ADCs, encoder/decoders, logic gates, memory circuits etc? Can ANYONE answer this. Please HELP!
